Discovery of an Indiana iron bridge

While following our map/directions app on the way to another historic bridge we were pleasantly surprised when we came up to another old iron bridge. This one has a lower profile, with no superstructure overhead. Typical of lots of smaller iron bridges, the deck is made of open grating that lets you look through the floor to the water below.

This bridge, tagged Brown County Bridge #33, known to locals as the Green Valley Road Bridge, is an iron pony truss design. The bridge spans the North Fork of Salt Creek. The nearly 90 foot long span was constructed in 1915 by the Cambria Steel Co. of Johnstown, Pennsylvania. Cambria was a very prolific builder in many midwestern states at the turn of the century.

Probably needs an engineer to have a look






The Green Valley Road runs through a beautiful part of Brown County, one of Indiana’s most visited counties. This small bridge adds to the charm of the road and surrounds. It is eligible for the National Register of Historic Places. The structure could use a coat of paint. Some rather noticeable damage has occurred on one side of an approach. This damage may or may not be structural and hopefully is not hazardous to the bridge.
